Thing:437314 at 50% scale Motor housing and stand
I printed http://www.thingiverse.com/thing:437314 at 50% scale and wanted to get it hooked up to a motor for testing to I threw this together. The .stl includes the motor casing, a stand that will need to be printed twice and a spacer that I found very useful in getting the fan in some form of alignment with the motor. My motor had an outer diameter of 24mm and a 2mm shaft.
